Description

Technical Field

[0001] This utility model relates to the field of car wash machine technology, and more specifically, to an anti-fall mechanism and a car wash machine. Background Technology

[0002] In existing car wash machines, there are no anti-fall structures for the top brush mechanism and the top blower mechanism.

[0003] Therefore, if the top brush mechanism or top blower mechanism of the car wash machine accidentally falls during the car wash process using existing technology, it will cause damage to the vehicle. Utility Model Content

[0004] The main purpose of this utility model is to provide a fall prevention mechanism and a car wash machine to prevent the top brush mechanism and the top blower mechanism from falling accidentally.

[0005] To achieve the above objectives, according to one aspect of the present invention, a fall prevention mechanism is provided, applicable to a preset mechanism. The preset mechanism is connected to the second end of a transmission member, so that the transmission member drives the preset mechanism to move vertically. The fall prevention mechanism includes: a fixed frame with multiple locking engagement parts distributed vertically; a locking member, which is interconnected with the preset mechanism and the second end of the transmission member, and has a normal state and a locked state. When the first and second ends of the transmission member are not broken, the locking member is in the normal state, and the locking member is in a non-locking engagement with each locking engagement part, so that the locking member moves vertically with the transmission member. When the first and second ends of the transmission member break, the locking member changes from the normal state to the locked state, so that the locking member locks with one of the locking engagement parts to prevent the preset mechanism from continuing to fall.

[0006] Specifically, the locking engagement part is a locking hole, and the locking member has a locking end; when the locking member is in the locked state, the locking end of the locking member is inserted into the locking hole so that the locking member and the locking engagement part are locked together.

[0007] Specifically, the locking element is rotatably arranged around a preset axis so that the locking element can switch between a normal state and a locked state; the preset axis is parallel to the horizontal direction.

[0008] Specifically, the locking member has a connecting end and a locking end. The locking end of the locking member is used to lock into a locking engagement part, and the connecting end of the locking member is connected to an actuating component. When there is no breakage between the first end and the second end of the transmission member, the force exerted by the transmission member on the locking member is greater than the force exerted by the actuating component on the locking member, so that the locking member is in a normal state. When a breakage occurs between the first end and the second end of the transmission member, the locking end of the locking member locks into a locking engagement part under the force exerted by the actuating component, so that the locking member changes from a normal state to a locked state.

[0009] In some embodiments, the connecting end and the locking end of the locking member are located on both sides of a preset axis, and the active component is a counterweight.

[0010] Furthermore, the fall arrest mechanism also includes a support shaft, and a locking element is rotatably mounted on the support shaft around its central axis; the central axis of the support shaft is a preset axis; a torsion spring is mounted on the support shaft, one end of which is connected to the connecting end of the locking element, and the other end of which is connected to the preset mechanism.

[0011] In some embodiments, the actuating component includes an elastic member having a first end and a second end disposed opposite to each other along its elastic extension direction; the first end of the elastic member is connected to the connecting end of the locking member, and the second end of the elastic member is connected to a preset mechanism; when the locking member is in a normal state, the elastic member is in a stretched state; when a break occurs between the first end and the second end of the transmission member, the elastic force of the elastic member causes the locking member to change from a normal state to a locked state.

[0012] Furthermore, the elastic extension direction of the elastic element is set at an acute angle to the vertical direction.

[0013] According to another aspect of the present invention, a car wash machine is provided, which includes a transmission component, a preset mechanism and the aforementioned anti-fall mechanism, wherein the preset mechanism is a blower mechanism or a roller brush mechanism.

[0014] Optionally, there are multiple transmission components, which together drive the preset mechanism to move in the vertical direction; there are multiple anti-fall mechanisms, with each transmission component corresponding to one anti-fall mechanism.

[0015] Applying the technical solution of this utility model, the fall protection mechanism is suitable for a preset mechanism, which is used to connect with the second end of the transmission member so that the transmission member drives the preset mechanism to move in the vertical direction; wherein, the transmission member has a first end and a second end arranged opposite to each other, and the first end of the transmission member is used to connect with the drive component so that the drive component drives the preset mechanism to move in the vertical direction through the transmission member.

[0016] The fall arrestor includes a fixed frame and locking components; the fixed frame is provided with multiple locking engagement parts distributed in the vertical direction.

[0017] The locking component, the preset mechanism, and the second end of the transmission component are interconnected; the locking component has a normal state and a locked state.

[0018] When there is no break between the first and second ends of the transmission component, the locking component is in a normal state, and the locking component is in a non-locking fit with each locking engagement part, so that the locking component moves with the transmission component in the vertical direction.

[0019] When a break occurs between the first and second ends of the transmission component, the locking component and the preset mechanism fall downwards together. At this time, the locking component changes from its normal state to a locked state so that it locks with one of the locking engagement parts, thereby preventing the preset mechanism from falling further.

[0020] The fall protection mechanism of this application is a purely mechanical structure, which can prevent the top brush mechanism and the top blower mechanism from accidentally falling, thereby avoiding damage to the vehicle caused by the accidental fall of the top brush mechanism or the top blower mechanism. In addition, the mechanical fall protection structure can eliminate potential electrical malfunctions. Attached Figure Description

[0042] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0043] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0044] This utility model provides a fall protection mechanism; please refer to [reference needed]. Figures 1 to 8 The fall arrestor is applicable to the preset mechanism 60. The preset mechanism 60 is used to connect to the second end of the transmission member 90 so that the transmission member 90 drives the preset mechanism 60 to move in the vertical direction; wherein, the transmission member 90 has a first end and a second end arranged opposite to each other, and the first end of the transmission member 90 is used to connect to the drive assembly 80 so that the drive assembly 80 drives the preset mechanism 60 to move in the vertical direction through the transmission member 90.

[0045] The fall arrest mechanism includes a fixed frame 10 and a locking element 20; the fixed frame 10 is provided with a plurality of locking engagement parts 11 distributed in the vertical direction.

[0046] The locking member 20, the preset mechanism 60, and the second end of the transmission member 90 are interconnected; the locking member 20 has a normal state and a locked state.

[0047] When there is no break between the first and second ends of the transmission member 90, the locking member 20 is in a normal state, and the locking member 20 and each locking engagement part 11 are in a non-locking engagement, so that the locking member 20 moves with the transmission member 90 in the vertical direction.

[0048] When the first and second ends of the transmission member 90 break, the locking member 20 and the preset mechanism 60 fall downwards together. At this time, the locking member 20 changes from the normal state to the locked state so that the locking member 20 locks with one of the locking engagement parts 11, thereby preventing the preset mechanism 60 from falling further through the locking engagement of the locking member 20 with one of the locking engagement parts 11.

[0049] Optionally, the transmission element 90 is a transmission bar. Optionally, the transmission bar is a transmission belt or a transmission chain; for example, the transmission belt is a belt.

[0052] In one first implementation where the locking member 20, the preset mechanism 60, and the second end of the transmission member 90 are interconnected, the locking member 20 and the preset mechanism 60 are respectively connected to the second end of the transmission member 90. In this implementation, if the locking member 20 is located on the side of the preset mechanism 60 closest to the first end of the transmission member 90, then when a break occurs between the first and second ends of the transmission member 90, the break point of the transmission member 90 will necessarily be located between the connection point of the locking member 20 and the first end of the transmission member 90.

[0053] The second implementation of the interconnection between the locking member 20, the preset mechanism 60, and the second end of the transmission member 90 is as follows: the preset mechanism 60 is connected to the second end of the transmission member 90, and the locking member 20 is connected to the preset mechanism 60, that is, the locking member 20 is connected to the second end of the transmission member 90 through the preset mechanism 60.

[0054] A third implementation of the interconnection between the locking member 20, the preset mechanism 60, and the second end of the transmission member 90 is as follows: the locking member 20 is connected to the second end of the transmission member 90, and the preset mechanism 60 is connected to the locking member 20, that is, the preset mechanism 60 is connected to the second end of the transmission member 90 through the locking member 20.

[0055] In this application, optionally, the locking engagement portion 11 is a locking hole, and the locking member 20 has a locking end. When the locking member 20 is in the locked state, the locking end of the locking member 20 is inserted into the locking hole to achieve a locking engagement between the locking member 20 and the locking engagement portion 11.

[0063] When a break occurs between the first and second ends of the transmission member 90, the force exerted by the transmission member 90 on the locking member 20 disappears. Under the force exerted by the action member 22 on the locking member 20, the locking end of the locking member 20 is locked into a locking engagement part 11, thereby changing the locking member 20 from the normal state to the locked state.

[0064] In this application, the first configuration of the action component 22 is as follows: the connecting end and the locking end of the locking member 20 are located on both sides of the preset axis, and the action component 22 is a counterweight 23.

[0084] Example 1

[0085] Please refer to this embodiment. Figures 1 to 5 .

[0086] In this embodiment, the action component 22 is configured in the first form, that is, the action component 22 is a counterweight 23, and the connecting end and the locking end of the locking member 20 are located on both sides of the preset axis.

[0087] When there is no break between the first and second ends of the transmission component 90, the force exerted by the transmission component 90 on the locking component 20 is greater than the force exerted by the counterweight 23 on the locking component 20 due to its own weight, so that the locking component 20 is in a normal state.

[0088] When a break occurs between the first and second ends of the transmission member 90, the force exerted by the transmission member 90 on the locking member 20 disappears. Under the force exerted by the counterweight 23 on the locking member 20 due to its own weight, the locking end of the locking member 20 is locked into a locking engagement part 11, thereby changing the locking member 20 from the normal state to the locked state.

[0089] In this embodiment, the fall protection mechanism also includes a fourth connecting component 27, the preset mechanism 60 is connected to the fourth connecting component 27, and the support shaft 21 is fixed on the fourth connecting component 27.

[0095] When a break occurs between the first and second ends of the transmission component 90, the force exerted by the transmission component 90 on the locking component 20 disappears. Under the combined action of the force exerted by the counterweight 23 on the locking component 20 due to its own weight and the force exerted by the torsion spring 211 on the locking component 20, the locking end of the locking component 20 is locked into a locking engagement part 11, thereby changing the locking component 20 from the normal state to the locked state.

[0097] Optionally, the other end of the torsion spring 211 is connected to the third connector 272, that is, the other end of the torsion spring 211 is connected to one of the fifth connecting parts 2721 of the third connector 272.

The central axis of the rotating shaft 612 is parallel to the horizontal direction. The rotating shaft 612 is connected to the fourth connecting component 27, that is, the rotating shaft 612 is connected to the second connecting member 271.

[0100] Specifically, the roller brush mechanism 61 also includes a power component 613 and a transmission mechanism. The power component 613 is connected to the first end of the rotating shaft 612 through the transmission mechanism to drive the rotating shaft 612 to rotate.

[0106] In this embodiment, the locking member 20 has a connecting hole 201, and the locking member 20 is sleeved on the support shaft 21 through its connecting hole 201; the center line of the connecting hole 201 coincides with the central axis of the support shaft 21.

[0107] In this embodiment, the counterweight 23 may optionally be a lifting lug.

[0108] Optionally, the second end of the transmission member 90 is connected to the counterweight 23, so that the second end of the transmission member 90 is connected to the locking member 20 via the counterweight 23. Alternatively, the second end of the transmission member 90 is connected to both the counterweight 23 and the locking member 20.

[0110] Example 2

[0111] Please refer to this embodiment. Figures 6 to 8 .

[0112] In this embodiment, the actuating component 22 is configured in a second manner, that is, the actuating component 22 includes an elastic element 24, the elastic element 24 having a first end and a second end disposed opposite to each other along its elastic extension and contraction direction; the first end of the elastic element 24 is connected to the connecting end of the locking component 20, and the second end of the elastic element 24 is connected to the preset mechanism 60.

[0113] When the locking element 20 is in the normal state, the elastic element 24 is in the stretched state.

[0114] When there is no break between the first and second ends of the transmission member 90, the force exerted by the transmission member 90 on the locking member 20 is greater than the force exerted by the elastic member 24 on the locking member 20, so that the locking member 20 is in the normal state and the elastic member 24 is in the tensile state.

[0115] When a break occurs between the first and second ends of the transmission member 90, the force exerted by the transmission member 90 on the locking member 20 disappears, and the stretched elastic member 24 retracts. Under the elastic force of the elastic member 24, the locking end of the locking member 20 engages with a locking mating part 11, thereby changing the locking member 20 from the normal state to the locked state.

[0143] Compared to the top brush anti-fall structure in Embodiment 1, the top blowing anti-fall structure in Embodiment 2 can withstand a larger load.

[0144] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0145] In the fall prevention mechanism applicable to the preset mechanism 60 provided by this utility model, the preset mechanism 60 is used to connect with the second end of the transmission member 90 so that the transmission member 90 drives the preset mechanism 60 to move in the vertical direction; wherein, the transmission member 90 has a first end and a second end arranged opposite to each other, and the first end of the transmission member 90 is used to connect with the drive assembly 80 so that the drive assembly 80 drives the preset mechanism 60 to move in the vertical direction through the transmission member 90.

[0146] The fall arrest mechanism includes a fixed frame 10 and a locking element 20; the fixed frame 10 is provided with a plurality of locking engagement parts 11 distributed in the vertical direction.

[0147] The locking member 20, the preset mechanism 60, and the second end of the transmission member 90 are interconnected; the locking member 20 has a normal state and a locked state.

[0148] When there is no break between the first and second ends of the transmission member 90, the locking member 20 is in a normal state, and the locking member 20 and each locking engagement part 11 are in a non-locking engagement, so that the locking member 20 moves with the transmission member 90 in the vertical direction.

[0149] When the first and second ends of the transmission member 90 break, the locking member 20 and the preset mechanism 60 fall downwards together. At this time, the locking member 20 changes from the normal state to the locked state so that the locking member 20 locks with one of the locking engagement parts 11, thereby preventing the preset mechanism 60 from falling further through the locking engagement of the locking member 20 with one of the locking engagement parts 11.

[0150] The fall protection mechanism of this application is a purely mechanical structure, which can prevent the top brush mechanism and the top blower mechanism from accidentally falling, thereby avoiding damage to the vehicle caused by the accidental fall of the top brush mechanism or the top blower mechanism. In addition, the mechanical fall protection structure can eliminate potential electrical malfunctions.

[0151] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0152] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0153] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
